Super Bowl Hotfix 1/30/14

The game caches data on your device so it can load back up quicker. So since it's an-app update it, the game calls the old cache files (that don't show the update) so that's why you have to force close the application for In-App updates so it will clear the game cache.

Ever noticed if you login on Wi-Fi, then log in on cellular like an hour later that it doesn't load? It cached the data from the Wi-Fi session and trying to open your game, but since it has a different internet connection it has trouble. So when you force-close the application, you can log back in easily in this scenario as well.
